Laptop’s Bluetooth partial functionality reasons?

Hello! I am a laptop user and I have the functionality of Bluetooth in my laptop. The problem is that when I transfer something from my laptop to some other device, let it be a mobile phone or another laptop, it works fine. I have transferred a lot of pictures and music from my laptop to other devices. But when I try to transfer something from another device to my laptop, it shows error that the transfer could not be completed properly. Why does this happen? If my laptop can send the data, it should be able to retrieve data as well, right? Any suggestions?
